Little is known bout M.K., the new clone which EW exclusively revealed, but the show’s co-creator John Fawcett described her as “a clone who has been self-aware for some time,” which proves to be both helpful and possibly dangerous to Sarah and the other clones. BBC America has previously released teasers hinting at the new clone’s presence in the season to come.
